Dementia vs. Alzheimer's: differences the family should understand

In families they're used as synonyms, but they're not. Understanding the difference helps you ask for the right evaluation, avoid assuming too much, and above all, care better.

Dementia: the umbrella

"Dementia" isn't a disease: it's a general term for a set of symptoms —memory loss, confusion, difficulty reasoning or doing daily tasks— that interfere with normal life. It has several possible causes.

Alzheimer's: the most common cause

Alzheimer's disease is the most frequent cause of dementia: a progressive process that affects memory, thinking, and behavior. Other causes include vascular dementia and Lewy body dementia. Only a doctor, with the proper evaluation, can determine the cause in each person: the family doesn't diagnose from what it reads online.

Why the difference matters: each cause has its own course and particularities, and that changes what to expect and how to accompany. What doesn't change with any of them: the person needs routine, patience, simple communication, and a safe environment. The diagnosis guides; daily care sustains.

How we care at home (without being clinical)

Our companionship for dementia and Alzheimer's is non-clinical: fixed routines, a calm and orderly environment, clear and unhurried communication, gentle redirection when agitated, constant supervision for safety, and logging changes for the family and the doctor. Higher assistance ($17 an hour on a weekly plan) is the option designed for these cases.

Common myths worth letting go

• "It's just old age, it's normal": normal aging doesn't prevent daily life. If it interferes, it deserves medical evaluation.
• "You have to make them see reason": arguing with someone who has dementia only creates distress for both. Redirecting calmly works better.
• "They don't understand anything anymore": they understand more than it seems, especially tone and emotions. Speaking to them with respect is never too much.
• "It's better not to tell them the diagnosis": each family decides with their doctor, but adapted honesty usually brings more peace than secrecy.

Caring for the family caregiver

Caring for someone with dementia is among the most draining tasks there are: the repetition of the same questions, the behavioral changes, the anticipatory grief of watching who they were fade little by little. The family member who cares needs real, periodic relief — not just "holding on" until breaking. Asking for help —whether taking turns with another family member or hiring a professional caregiver for a few hours or days— isn't failing: it's what lets you keep caring well long-term without getting sick trying.

Communication that works: one idea per sentence, showing as well as telling, giving time to respond, validating the emotion first ("I'm here with you"), and avoiding correcting in public. These aren't clinical techniques: they're human treatment with method. And they work.
